All art is infested by other art.
Whatever else art is good for, its chief effectiveness lies in propagating more art.
...it is in the nature of original contemporary art to present itself as a bad risk. And we the public...should be proud of being in this predicament, because nothing else would seem to us quite true to life; and art, after all, is supposed to be a mirror of life.
If a work of art or a new style disturbs you, then it is probably good work. If you hate it, it is probably great.
